i started my first sencha app by creating a skeleton using the sencha-generator. After some tweaking and fixing i got that running.
then i started to implement my first simple app. A week-list with infos for each day. I want to simply retrieve a JSON string and print it to a list. Then, when i touch a list-item, a detail page should come up. so far so good.
My Problem is, that the data is not rendered on the list.
Some problem with the store i guess, as i had to replace

store: carmaCal.stores.days

with

initComponent : function() {
store: Ext.getStore('days')
}

in the list-component to make it somehow start without errors.

I follow the MVC-structure, so i have my day-model and -store in Day.js:
